我国水力采煤发展的若干战略问题

Several Strategical Issues on Developemnt of Hydraulic Mining in China

我国煤炭可采储量的10％～20％适合采用水力采煤技术进行开采。今后应根据不同的煤层条件、生产技术条件和社会需求条件,因地制宜,以最好的技术经济效益为目标,不断完善和发展不同类型、不同规模的水采技术,为我国煤炭生产机械化做出贡献。

The coal mining practices over the last 30 years at home and abroad shown that the hydraulic mining is one of the effective technical approches to the coal mining mechanizations. About 10 to 20%of China mineable coal reserves are suiuable to be won by the hydraulic mining. In the future, the hydraulic mining should be based on verious production, social and local conditions to introduce advanced science and technical achievements from other industries, including the other mining methods and technologies. To reach a target with a best results of technology and economy, the hydraulic mining should be contin-eously to be improved and developed with different type and scale in order to make a contribution to the mechanization of coal mining in China.
